Maria Sharapova rounded out the quarterfinals of the Sony Open Tennis in Miami by beating Klara Zakopalova 6-2 6-2 after failing to convert four match points in the final game that had five deuces. This is Sharapova’s eighth appearance at the tournament and she played the finals four times but never made it to the winner’s trophy. Her quarterfinal will be a rematch of her recent Indian Wells quarterfinal – she faces Sara Errani, who lost the first set of her fourth-rounder against Ana Ivanovic in quick 23 minutes, before working her way to a 1-6 6-4 6-2 victory. Sharapova is 3-0 against Errani, including her 7-6(6) 6-2 win at this month’s Indian Wells.
Quarterfinal pairs: Serena Williams (1) vs. Li Na (5), Agnieszka Radwanska (4) vs. Kirsten Flipkens (30), Sara Errani (8) vs. Maria Sharapova (3), Jelena Jankovic (22) vs. Roberta Vinci (15). (source: WTA Tour, photo: © Neal Trousdale)
